From eda736a0f4691a5bcd1b2178689e8ddcbf52b426 Mon Sep 17 00:00:00 2001 From: Julian Maurice Date: Thu, 12 Apr 2018 20:42:13 +0200 Subject: [PATCH] Bug 20582: Turn Koha into a Mojolicious application This patch is a proof-of-concept of Koha as a Mojolicious application This has several benefits: - Development setup is easier. No need for apache or nginx. Just run `morbo bin/intranet` or `morbo bin/opac` and go to http://localhost:3000 (URL rewrites and static files are handled by the app) - apache2/nginx configuration is simpler too (an example of nginx configuration is included in the patch) - starman and plack middlewares can still be used for debug or gzip compression for instance (see app.psgi) - Using Test::Mojo we can test the whole application, as we do with the REST API (which is a Mojolicious application too) - It opens a way for converting CGI scripts into Mojolicious controllers and actions (even if that's not possible at the moment because of the authentication code) It uses the same mechanism as Plack::App::CGIBin to deal with CGI scripts, so it should be equivalent in terms of performance How to test ? - Run `morbo bin/intranet`, then go to http://localhost:3000/ and try to find bugs. Check the REST API at http://localhost:3000/api/v1 - Run `morbo bin/opac`, then go to http://localhost:3000/ and try to find bugs. Check the REST API at http://localhost:3000/api/v1 - Run `starman -l :5000 -l :5001` and verify that intranet (http://localhost:5000) and opac (http://localhost:5001) work normally - Read the code (and the comments), it's not very long Signed-off-by: Victor Grousset/tuxayo --- Koha/App/Intranet.pm | 85 +++++++++++++++++++++++++++++ Koha/App/Opac.pm | 85 +++++++++++++++++++++++++++++ Koha/App/Plugin/CGIBinKoha.pm | 100 ++++++++++++++++++++++++++++++++++ Koha/App/Plugin/RESTV1.pm | 32 +++++++++++ app.psgi | 52 ++++++++++++++++++ bin/intranet | 43 +++++++++++++++ bin/opac | 27 +++++++++ etc/nginx.conf | 33 +++++++++++ 8 files changed, 457 insertions(+) create mode 100644 Koha/App/Intranet.pm create mode 100644 Koha/App/Opac.pm create mode 100644 Koha/App/Plugin/CGIBinKoha.pm create mode 100644 Koha/App/Plugin/RESTV1.pm create mode 100644 app.psgi create mode 100755 bin/intranet create mode 100755 bin/opac create mode 100644 etc/nginx.conf diff --git a/Koha/App/Intranet.pm b/Koha/App/Intranet.pm new file mode 100644 index 0000000000..3eddd49fab --- /dev/null +++ b/Koha/App/Intranet.pm @@ -0,0 +1,85 @@ +package Koha::App::Intranet; + +# Copyright 2020 BibLibre +# +# This file is part of Koha. +# +# Koha is free software; you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# Koha is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
